Assessment of land cover relocation incorporating the effects of human activity in typical urban and rural catchments for the design of management policies
The study used multivariate analysis to examine how the total nitrogen (TN) outflow in river water is related to land use and human activity in two different urban–rural catchments: Asakawa in Tokyo and Shubuto in Hokkaido.

The male/female ratio of fetal deaths and births in Japan
Since the 1950s, the ratio of male-to-female births has been declining in several industrial countries. In Japan, the proportion of male births decreased from 0.517 in 1970 to 0.513 in 1996. Although many factors have been identified as possibly affecting the male/female ratio of births, it is noted that the change in the male/female ratio of deaths in the country may have led to the change in the male/female ratio of births.
Carrying capacity: A model with logistically varying limits.
We introduce an extension to the widely-used logistic model of growth to a limit that in turn allows for a sigmoidally increasing carrying capacity, that is, the invention and diffusion of technologies which lift the limit. We study the effect of this dynamic carrying capacity on the trajectories of simple growth models, and we use the new model to re-analyze two actual cases of the growth of human populations. English and Japanese examples with two pulses, or one change in limit, appear to verify the model. (Author's abstract)
Instability, investment, disasters, and demography: natural disasters and fertility in Italy (1820-1962) and Japan (1671-1965).
Using regional data, the paper presented a detailed investigation of the effects of environmental and economic instability on fertility and its components in both Italy and Japan using regional data.
